1kVA short-depth online UPS for network and security racks

The Echo ECH1000RMi2U is a 1000VA / 900W single-phase, true online double-conversion UPS designed by Uniti Power for network switches, firewalls, security and CCTV systems, retail point-of-sale and small servers. At 2U high and only 428mm deep, it fits comms racks and wall cabinets where a full-depth UPS will not, and its two internal 12V 9Ah batteries give a typical 3.8 minutes at full load.

Online double conversion means connected equipment never runs directly from the mains. Incoming AC is converted to DC and then regenerated by the inverter as a clean, regulated sine wave, so sags, spikes, frequency shifts and waveform distortion are filtered out before they reach the load. When the mains fails there is nothing to switch over: the batteries simply take over feeding the inverter, with a 0ms transfer. A wide 90-275VAC input window keeps the UPS off battery through unstable supply conditions, which helps to extend overall battery life.

Where the ECH1000RMi2U is used

Uniti Power's Echo range is built for networking, security, retail and distributed IT. Typical ECH1000RMi2U installations include network and communications racks, security and CCTV systems, retail and POS equipment, edge computing, and small servers, firewalls and switches.

Key capabilities

• Zero transfer time: 0ms between inverter and battery operation, so the output does not break during a power cut.
• Regulated output: pure sine wave, ±1% voltage regulation and under 2% THDv on linear loads.
• 0.9 output power factor: 900W of usable real power from the 1000VA rating.
• Wide input tolerance: 90-275VAC ±5VAC and 40-70Hz ±0.5Hz, with an input power factor above 0.99.
• Efficiency: 89% in line mode and 85% in battery mode.
• Automatic bypass: if the inverter is overloaded or develops a fault, the load transfers to bypass in under 4ms to maintain continuity.
• Overload handling: 100-105% continuously and 105-130% of rated load for 60 seconds.
• Quiet running: under 50dB (ISO 7779, 1m from the front, without buzzer), suited to offices, shops and comms rooms.

Runtime from the internal batteries

The ECH1000RMi2U holds two internal 12V 9Ah batteries in a 24V DC system, recharged by a 1A charger to 90% in around 5 hours.

This is a self-contained internal-battery model. Where a site needs runtime that can be scaled with external battery modules, the Echo ECH3000RMi2UER extended runtime model is designed for that role.

Runtimes are typical values for new, fully charged batteries at 25°C, provided as a guide only. Actual runtime depends on battery age, temperature and the type of load.

Installation in shallow racks and cabinets

The ECH1000RMi2U measures 439.8 x 88 x 428mm and weighs 13kg. Rack ears are supplied, and the user manual recommends keeping 200mm of free space behind the rear panel for ventilation. Power comes in through an IEC C14 inlet using the supplied input power cord, and the user manual shows four IEC C13 output sockets on the rear panel.

The programmable LCD shows load level, battery capacity, input and output values, alarms and the current operating mode. Output voltage can be set to 208, 220, 230 or 240VAC, with 230V as the default.

Monitoring and communications

RS232 and USB ports are fitted as standard, along with a dry-contact port for emergency power off (EPO) and remote on/off (ROO), so the UPS can be tied into building safety systems or remote controls. The short-depth external slot accepts the optional UPNETG2S short Gigabit network management card, which works with WinPower G2 and SPS G2 software for real-time status, event notifications and automated shutdown of connected systems.

Standards, warranty and support

The ECH1000RMi2U is CE marked and IP20 rated. The Echo user manual lists EMC to IEC 62040-2 Category C2 and safety to EN IEC 62040-1.

Registered Echo products in the UK carry a 3-year parts warranty and 1 year on batteries. See warranty information for full terms and register your UPS once it is installed. For help on site, Uniti Power also offers installation and commissioning and technical support.

What's in the box

The user manual's shipping list covers the ECH1000RMi2U UPS, input power cord, a pair of rack ears and the user manual. RS232 and USB cables and a communication card are listed as optional items.

Echo ECH1000RMi2U questions answered

Is the Echo ECH1000RMi2U a true online UPS?
Yes. The ECH1000RMi2U uses online double conversion, so the inverter supplies the load at all times and the transfer to battery is 0ms.

How deep is the ECH1000RMi2U?
428mm. With a height of 88mm (2U) and a width of 439.8mm, it suits shallow comms racks and wall cabinets.

How long will the ECH1000RMi2U run on battery?
Typically 3.8 minutes at full load, 11.8 minutes at half load and 23 minutes at 25% load from its two internal 12V 9Ah batteries.

Can the ECH1000RMi2U be monitored over the network?
Yes. Fit the optional UPNETG2S short network management card in the external slot and use WinPower G2 for monitoring, alerts and safe shutdown.
